Hi Simon,

Having the same issue.
For some reason i can't run it in compatibility mode for IE8, but works fine in the other browsers.
Since nobody is currently developing this project, i think we're screwed!
 

Solution anybody?

The problem seems to be that the chat message updates received from the server have a prefix code on them that wasn't there before; I'm not sure if this is by design or a bug.  The XML parsers used on other browsers happily ignore this prefix, but MSXML (Internet Explorer's XML parser) doesn't like it. So I tweaked the JavaScript for the Chat module to discard this prefix if present.

To apply this workaround, you need to edit DesktopModules\Chat\DnnChat.js:

• Go to line 59. The preceeding lines should be:

  function receiveChatMessage(result, context)
  {
      try
      {
  	

• Paste the following:

          // WORKAROUND: MSXML is choking on a lead character that we're getting.
          // So strip off anything before the opening '<'
          while ((result.length > 0) && !(result.charAt(0) == '<')) {
              result = result.slice(1);
          }
  
  	

I've tested this with IE8 (current), Safari (current), Firefox (recent), and Google Chrome (current).

Hope this helps!
